Problem Getting Prim's Group Name

In a prim I created, I have a script with the following code:

list details = llGetObjectDetails(llGetKey(), [OBJECT_GROUP]);
string name = llKey2Name(llList2Key(details, 0));
llOwnerSay("["+name+"]";

The llGetObjectDetails call returns a one-element list containing the prim's group key. The key appears to be a valid key, but passing it to llKey2Name() always returns an empty string (i. e., the llOwnerSay always outputs []). I have verified that the prim DOES have a valid group set for it. This is a regular single prim. It is not part of a linkset. It is not an attachment.

Anyone know why this is not working? Thanks!!

llKey2Name won't return the name of a Group.

there is a work around posted here some where, using an http call to the SL web server with the group key and then fetch the group name from the web page

Oh. Wonderful. That should probably be documented in the wiki entry for llKey2Name(). I wonder if that is intentional, or an LSL oversight/bug. I suppose there's no way to get the name of the group set for a prim. (Other than reaching out to an external source.) Thanks for the replies.

actually it is documented, specifically returns names for avatars/agents and prims that are in the sim.

it would seem semi intentional, since th function is requesting sim data, and sims don't store much in the way of group data.
